【摘要】 软件缺陷是衡量软件项目可靠性的重要指标,缺陷的预测技术也是软件质量度量的核心问题。在软件缺陷产生及生长过程机理分析的基础上,将缺陷分为潜藏、被发现和被修复三种状态,建立了在失信因子和约束因子的共同作用下,缺陷状态动态转移的微分方程模型,并对其平衡点的稳定性及失信因子的边界条件进行了分析。同时,对NASA中一个软件项目进行实证分析,利用软件测试及缺陷的修复记录对系统中潜藏的缺陷进行预测,结果表明模型的合理性。更多还原

【Abstract】 Software defect is the key measure of software reliability,and predicting defect is also one of the core topics of software quality evaluation.Based on analysis of mechanism of software defect growth,the states of defect are divided into hidden,be detected and repaired.Considering the combined effect of distrustable factors and constrained factors,the differential equation model for defect states transferring is proposed in this paper.The stability of equilibrium point and boundary condition of distrustable factors are also analyzed.Meanwhile,a real project of NASA is analyzed,the hidden defects are estimated by the record of detected and repaired defect,and the results are exemplified the rationality of the model.更多还原
